Now that it's possible, I'd like to install IE10 on my Win7 machine. However, I need to continue to run IE9 for testing purposes. Has anyone figured out a way to do this without using the VMs? For some reason this issue is impervious to googling...

Microsoft release virtual machines which are centered around testing IE in various configures. –  Ramhound Feb 28 '13 at 19:12
Using the Developers Tools (F12) you can switch to all recent versions of IE. –  ZippyV Feb 28 '13 at 19:24

You can do it with an app called IE Tester.

It'll allow you to use all IE versions back to 5.5, but, ZippyV's solution (using developer tools) would work pretty much as well (better in some cases)

+1. IE Tester is a very handy program. –  James Jul 26 '13 at 9:07

you can't do it simultaneously that i am aware of, but if you want to use both without using a vim, simply uninstall IE10 everytime you need to use IE9; yes it is tedious, annoying, and not ideal. You actually can't "uninstall", but when you go to uninstall software, click on the option for windows updates, you'll find your ie10 install there.
